Hi There,

I am a second year Digital Art and Technology Degree student who wants to devise a simple wireless mesh network app where without internet connection two or more mobile phones can text message each other using bluetooth technology.

Can an app be made using MIT App Inventor 2 ?

Regards
Roger

the following example uses classic bluetooth
for classic bluetooth you have to use separate bluetooth components for each connection, I don't know, if this is the same for BLE

you also should be able to do this using BLE

Probably you cannot do this with BLE, because, although the BLE extension can act as a Server, most phones cannot.
Cheers, Ghica.

I would second Ghica's position. Right now our BLE extension only acts as a Central in Bluetooth parlance. That means that it can connect to other devices acting as Peripherals, but not to other Centrals. We have discussed introducing a BLE client extension that would allow the app to act as a Peripheral as well, but that functionality partly depends on what hardware the device manufacturer decided to include.

But Taifun's example, using < 4 BT should work fine on most phones.
Cheers, Ghica
